After seeing him on the Colbert Report (or was it the Daily Show?) and hearing about how he’s the “World’s Most Wanted Hacker”, I had to pick up Ghost in the Wires by Kevin Mitnik.
I honestly have only read the forwards and introduction so far. I got stopped before the first chapter because the following tantalizing hidden message hung at the start:
yjcv ku vjg pcog qh vjg uauvgo wugf da jco qrgtcvqtu vq ocmg htgg rjqpg ecnnu?
It’s a code, of course, so I had to give it a go. Looking over it a bit, you’ll notice the letter ‘g’ appears quite often (thanks Ghostwriter). I figured it must be a letter replacement code then, where each letter is replaced by another. Starting with ‘g = e’, I just typed in the rest of the alphabet, and lo and behold, the following decoder ring works!
true: a b c d e f g h i j k l m n o p q r s t u v w x y z
code: c d e f g h i j k l m n o p q r s t u v w x y z a b
Using it on the above message, you get:
what is the name of the system used by ham operators to make free phone calls?
The answer to which is “autopatch“.
